Galvalume Steel Coil Manufacturer



BOMIS is a Chinese galvalume steel coil manufacturer. We have the ability to supply AZ20-150g/square meters, alvalume to meet customers’ requirements for use in highly corrosive areas. We ensure that the weight of the metallic coating does not cut corners, and we have the equipment to detect it.


Feature



Galvalume steel coil has good corrosion resistance. It can balance the protective and repair effects of zinc with the anti-corrosion effect of aluminum, extending the service life of steel sheets.

Galvalume steel coil has relatively good heat resistance and will not change color when exposed to temperatures of around 316 degrees for a long time. It still has good antioxidant properties at a temperature of 677 degrees.
